The Diagnostic / The Situation
Nissan’s announcement to focus on creating ‘cool cars’ again has sparked excitement among car enthusiasts. To build a sporty lineup, it’s essential to understand the technical background of what makes a vehicle ‘cool’ and ‘sporty’. A sporty vehicle typically has a combination of high-performance capabilities, agile handling, and a sleek design. Nissan’s past models, such as the GT-R and 370Z, are examples of sporty vehicles that have gained a cult following.

Symptoms or signs of a vehicle that needs a sporty makeover include sluggish acceleration, poor handling, and a lackluster design. These issues can be addressed by upgrading the engine, suspension, and aerodynamics of the vehicle.
Technical Deep Dive
A sporty vehicle’s engine is typically equipped with high-performance components such as forged pistons, performance camshafts, and a free-flowing exhaust system. The suspension system is also critical, as it needs to provide a balance between comfort and handling. A sport-tuned suspension with stiffer springs and shocks can improve handling, while also providing a comfortable ride.
Common failure points in a sporty vehicle include the engine’s cooling system, transmission, and brakes. The plastic impeller in the water pump can fail, causing overheating issues. The transmission’s clutch pack can wear out, leading to slippage and poor acceleration. The brakes can also overheat, causing brake fade and reduced stopping power.

Safety Warnings
When working on a vehicle’s engine, suspension, and brakes, it’s essential to take necessary safety precautions. Wear protective gear, including gloves, safety glasses, and a face mask. Ensure the vehicle is securely lifted and supported before starting work.
Step-by-Step Guide
Upgrading the Engine
Step 1: Remove the Intake Manifold
Remove the intake manifold to access the engine’s internals. Use a 10mm socket to remove the bolts, and gently pull the manifold away from the engine.
Step 2: Install Forged Pistons
Install forged pistons to improve the engine’s performance and durability. Use a piston ring compressor to install the rings, and ensure the pistons are properly aligned.
Step 3: Install Performance Camshafts
Install performance camshafts to improve the engine’s power output. Use a camshaft alignment tool to ensure proper alignment, and torque the bolts to the specified value (20 Nm).
Upgrading the Suspension
Step 1: Remove the Coil Springs
Remove the coil springs to access the suspension’s internals. Use a suspension compressor to compress the springs, and remove the retaining ring.
Step 2: Install Sport-Tuned Shocks
Install sport-tuned shocks to improve the vehicle’s handling. Use a shock absorber compressor to compress the shocks, and torque the bolts to the specified value (30 Nm).
Step 3: Align the Wheels
Align the wheels to ensure proper tracking and handling. Use a wheel alignment tool to adjust the camber, toe, and ride height.
Upgrading the Brakes
Step 1: Remove the Brake Pads
Remove the brake pads to access the brake rotors. Use a brake pad spreader to push the pads away from the rotors.
Step 2: Install Performance Brake Rotors
Install performance brake rotors to improve the vehicle’s stopping power. Use a brake rotor resurfacing tool to resurface the rotors, and torque the bolts to the specified value (25 Nm).
Step 3: Bleed the Brake System
Bleed the brake system to remove any air pockets. Use a brake bleeding kit to pump the brakes, and check for any leaks.
Pro Tips & Common Mistakes
Don’t over-tighten the engine’s bolts, as this can cause damage to the engine block. Use a torque wrench to ensure the correct torque value is applied.
A common mistake when upgrading the suspension is to overlook the importance of proper alignment. Ensure the wheels are properly aligned to avoid uneven tire wear and poor handling.
Cost Analysis: DIY vs Mechanic
The cost of upgrading a vehicle’s engine, suspension, and brakes can vary depending on the components used and the labor involved. A DIY approach can save on labor costs, but may require specialized tools and expertise.
| Component | DIY Cost | Mechanic Cost |
|---|---|---|
| Engine Upgrade | $2,000-$5,000 | $5,000-$10,000 |
| Suspension Upgrade | $1,000-$3,000 | $3,000-$6,000 |
| Brake Upgrade | $500-$1,000 | $1,000-$2,000 |
Frequently Asked Questions
What is the best way to improve a vehicle’s handling? The best way to improve a vehicle’s handling is to upgrade the suspension system, including the shocks, springs, and sway bars.
How can I increase my vehicle’s power output? You can increase your vehicle’s power output by upgrading the engine’s internals, such as the pistons, camshafts, and exhaust system.
What are the benefits of using forged pistons? Forged pistons provide improved durability and performance, as they can withstand higher compression ratios and engine speeds.
How often should I bleed my brake system? You should bleed your brake system every 10,000-15,000 miles, or as recommended by the manufacturer.
Can I upgrade my vehicle’s engine and suspension myself? Yes, you can upgrade your vehicle’s engine and suspension yourself, but it’s recommended to have experience and specialized tools to ensure a proper installation.
